Definition ∞ Anti-virus evasion refers to methods used by malicious software to avoid detection by security programs. These techniques allow malware to operate without being flagged, often by altering its code, behavior, or communication patterns. Sophisticated evasion tactics can include polymorphism, metamorphism, obfuscation, and rootkit functionalities, all designed to circumvent signature-based or heuristic detection mechanisms. Such methods pose substantial risks to digital asset security and blockchain integrity by enabling unauthorized access or data corruption.
Context ∞ The ongoing challenge of anti-virus evasion remains a critical concern within cybersecurity, particularly as threat actors increasingly target cryptocurrency exchanges and individual digital wallets. Developers of security solutions continuously update their detection capabilities to counter novel evasion techniques. Understanding these methods is essential for assessing the vulnerability of platforms and the efficacy of protective measures reported in financial news.
